Hi, since upgrading a few servers and all of our desktop machines from Red Hat to Fedora, my users have started noticing a lot of stale NFS handle errors. I'm not entirely sure what it means to be honest. Anyway, has anyone else experienced that problem, and would they happen to have a solution?

The only time I've run across this where there were a lot of stale handles was when the server's network card was flaky. ifconfig showed a huge number of dropped packets - replaced the card and haven't had any problems since. So that might be the first place to look...

You won't necessarily see dropped packets with dmesg - you have to look at the stats from ifconfig. Just pointing out one starting point... Another thing you can try is to set the read/write block sizes: rsize=8196,wsize=8196 seems to work well for the servers I have set up.

On my home systems, I actually got real paranoid about this kind of issue and I restart the NFS server every night/morning when I know there's no activity on it (5 AM, if you're curious).
